New Bat House Research Project

Loss of natural homes in caves and old-growth forests is one of the greatest causes of bat decline worldwide. Unfortunately, many former roosts can never be replaced, leaving an increasingly urgent need for alternative shelter. Wildlife Biologist, Steve Barlow, was one of the first to test the suitability of extra large designs, and he has been experimenting for nearly 20 years. Recently he has supplied his Big Bat House design to nature centers, city parks, wildlife refuges, farmers and private landowners.

Last October, Merlin met with Steve and they agreed to collaborate in developing a new, design that they hope will be even more attractive to bats. Their research proposal was generously funded by MTBC members, Joe and Sharon Goldston, with additional help from Steve. In early April Merlin spent two days with Steve and his construction crew in Kansas brainstorming anticipated improvements.

The result is a new modular design that is much less costly to build and lighter in weight. We also anticipate it’s being even more attractive to bats. It can be mounted on just two instead of four poles, and when a first module fills, more can be added, each one housing up to 4,000 bats. Based on past experience it is quite likely that, at some locations tens of thousands can be attracted, as ability to expand will be unlimited.
